Abstract
922,798. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. April 19, 1961 [April 27, 1960], No. 14138/61. Drawings to Specification. Class 40 (4). In a system employing remote concentrators wherein communication between a concentrator and the exchange is by means of pulse code modulation on a channel of a time division multiplex system using separate go and return highways as described in Specification 921,384, each line is allotted a free time slot in the multiplex linking its concentrator to the exchange, the information received at the exchange from one party to a call in one time slot being transposed to the time slot allotted to the other party to the call before being retransmitted to the concentrator serving the other party. The transposition is effected by choosing the taps of a tapped delay line which introduce the required delays. A plurality of interconcentrator links are provided in order that connections may be extended to different concentrators in the same time slot.
